DYEING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 417,625, dated December'17, 1889.

Application filed August 28, 1889. Serial No. 322,218. (No model.)

To all whom; it may concern.-

Be it known that 1, Tom B. BoWnRs, of Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Dyeing Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which Figure 1 is a central longitudinal section through my improved dyeing apparatus. Fig. 2 is a transverse section of the vat and end view of cylinder. Fig. 3 is a transverse sectional View of cylinder. Fig. 4 is a detail view, enlarged, of the door-fastenings. Figs. 5 and 6 are side and end views of the journal-box casting for the worm-screw. Fig. 7

is a sectional detail of the door-fastenings.

This invention is an improvement in dyeing apparatus; and its object is to construct a machine by which the articles to be dyed can be submerged in the dye and slowly moved therethrough, doing such work better, more quickly, and more thoroughly than can be done by hand. To accomplish this result I have invented a machine which embodies the following construction and arrangement of parts. I

Referring to the drawings, A designates a tank or vat of any suitable construction adapted to contain the dye.

B designates a cylinder lying partly within the vat and supported by a transverse shaft O, passing axially therethrough, said shaft being supported exterior to the cylinder in bearings D D, mounted on the supports 0 C at the ends of and outside the vat, substantially as shown. The cylinder is formed of two heads 13 B of proper diameter and flanged on their peripheries for uniting them to the edges of the cylindrical shell B This shell is made of sheet metal and is numerously perforated to permit ready flow of the dye therein when revolving in the vat.

B B are cast-metal trunnions secured to the exterior faces of heads B and supporting the same upon the shaft O. In order to stiffen the heads, I attach angle-irons B to their inner faces. Four or more of said irons der.

may be employed, and they radiate from the center to periphery of heads, as shown.

The cylinder is divided into compartments (two, as shown) by means of a central diametrical and longitudinal partition of metal, preferably, which iscomposed of two sheets B B extending from the shaft 0 to the shell B having their outer edges flanged and united to the shell by suitable bolts or rivets, and their inner ends are bent over and embrace the shaft O, being united, as shown, around the shaft, so as to protect it from injury by the dyeing-fluid, as shown. At the center of each compartment and secured to and projecting inwardly from the shell B is a series of studs or fingers B B, as shown. One of the heads B is provided with doors B B closing openings therein through which access can be had to the compartments in the cylinder. These doors are securely closed by means of latch-pieces B and hand-nuts B", working on proper bolts, as shown.

On the end of shaft 0 is mounted a worm gear-wheel F, which is driven by a Worm H on a shaft H, that is driven in any suitable manner from any convenient source of power, so as to impart a slow rotation to the cylin- This worm-shaft H is mounted in a journal-box casting H which is formed with bearings H H for said shaft and an interme diate hollow dished portion H in which the worm rests and in which oil can be placed to lubricate the wheel or gearing.

Obviously the cylinder could be divided into four or more compartments, if found desirable.

The operation is substantially as follows: The vat A is filled with a dye of the desired color and strength, the cylinder, as will be evident, being partly submerged in such dye. The material to be dyed is then placed inthe uppermost compartment and the machinery set in motion. Thus the cylinder is slowly revolved and the material is carried down into the dye and through the same. While the material in one compartment is in the dye, if the cylinder be revolving slowly enough, or it can be stopped, material already treated in another chamber can be removed and fresh material added, so that the dye liquid is continually in use for dyeing material in different batches, and the loss of time incident to ordinary dyeing methods and apparatus, wherein the material is placed direct in the vat and removed therefrom before other material can be put in position for dyeing, is saved. The pins on the shell or studs assist in forcing the material below the surface of the dye by catching the articles as the cylinder revolves and pulling or drawing the same down with them into the dye.

\Vhat I claim, and desire to protect by Letters Patent, is-

1. The combination, with a vat containing the dye liquid, of a cylinder mounted therein upon a central shaft and having an outer perforated shell, internal longitudinal partitions secured to the shell at their outer edges and to each other at their inner edges, so as to inclose and protect the shaft from the dye, and having openings in its ends closed by suitable doors, substantially as described.

2. The combination, with the vat, of the cylinder having an outer perforated wall, a series of internal horizontal sheets secured to the wall and forming or secured to a sleeve surrounding the shaft and dividing the interior of the cylinderinto longitudinal compartments, the angle-irons on the inner faces of the cylinder-heads for supporting the ends of the sheets, and the doors in the head of the cylinder communicating with the respective compartments thereof, substantially as specified.

3. The combination, with the vat, of the cylinder having an outer perforated wall, a-

series of internal horizontal sheets secured to the wall and to or forming a sleeve surrounding the shaft and dividing the interior of the cylinder into longitudinal compartments, the an gle-irons on the inner faces of the cylinderheads for supporting the ends of the sheets and the doors in the head of the cylinder communicating with the respective compartments thereof, and the series of inwardly-projecting fingers on the shell of the cylinder in each compartment, all substantially as and for the purpose described.

4. The combination of the vat and the cylinder B, having heads B, cylindrical perforated shell 13 partition-plates B B and fingers B B with the shaft C, protected by the inner ends of plates from the dye, supporting said cylinder, the framesupports for said shaft, and the worm-gearing for driving the same, substantially as described.

5. The combination of the vat A, for holding dye liquid, with the cylinder B, having heads 18, irons B shell B perforated as described, fingers B, doors B and partitionplates B 13", and the shaft C, worm-gear F, worm H, shaft II, and casting 11 all constructed and arranged to operate in the manner and substantially as specified.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
